Starting from 5-alkyl-4-amino-4H-1,2,4-triazole-3-thiols and substituted chloroacetanilides, the corresponding (5-alkyl-4-amino-4H-1,2,4-triazol-3- ylsulfanyl)acetanilides were synthesized. The products underwent intramolecular cyclization in boiling phosphoryl chloride to afford 3-alkyl-6-arylamino-7H-[1, 2,4]-triazolo[3,4-b][1,3,4]thiadiazines. 3-Alkyl-6-aryl-7H-[1,2,4]triazolo[3,4- b][1,3,4]thiadiazine hydrobromides were obtained by reaction of 5-alkyl-4-amino-4H-1,2,4-triazole-3-thiols with substituted phenacyl bromides.
